GRAIN-SEPARATOR- Specification of Letters Patent.

Patented June 11, 1907.

Application filed February 16, 1907. Serial No. 357,729.

To all, whom it may concern.-

Be it known that 1, JOHN FEEHERY, a citizen of the United States,residing at Campus, in the county of Livingston and State of Illinois,have invented certain new and useful Improvements in GrainSeparators, ofwhich the following is a specification.

This invention is a grain separator or cleaner designed particularly foruse in connection with elevators, to clean the chaff and dirt from thegrain after it is delivered. from the wagon or other localtransportation device and before it is conveyed into the elevator.

Grain as it comes to the elevator is frequently unclean or poorlyseparated, and dirt is frequently the cause of rotting or heat ing inthe elevator bins.

The object of this invention is to provide an improved separator of thegravity type, utilizing an air blast toblow out the chaff and dirt asthe grain passes from the dump to the conveyer of the elevator house.

The invention is illustrated in the accompanying drawings, in whichFigure 1 is a sectional elevation of the invention. Fig. 2 is a plan ofthe blower head.

Referring specifically to the drawings, 6 indicates a raised floor ordriveway leading to the tilting dumping platform 7, which is controlledby a lever 8, the particular means for operating the platform and .forholding a wagon 9 thereon forming no part of this invention.

Under the dump, in position to receive the grain from the wagon or othervehicle, is a hopper 10 which is connected at the bottom by a grain leg11 to a conveyer 12 leading to another part of the elevator or elsewhereas desired. Located within the hopper is a false bottom 13 provided withan opening controlled by a slide valve 14 which may be opened or closedby means of ropes 15 which extend over guide pulleys 16 and thence outthrough the floor 6 in convenient position to be manipulated from above.Located directly under the saidvalve opening is a conical grain spreader17, supported by a standard 18, and the grain falls on this spreaderafter passing the valve. Under the spreader is a blower head 19 having acurved face 20 provided with openings 21, the face being curved toextend partly around and close to the stream of grain which falls fromthe spreader. The blower head receives its blast from a fan 22, throughthe tube 23, the fan being preferably located above the floor and thetube extending conveniently down through the hopper. Located within thehopper, opposite to the blower head 19, is the enlarged mouth 24 of atube 25 which extends upwardly at an incline along the side of thehopper, and discharges at 26 to waste.

In the operation of the invention, the grain is dumped from the wagoninto the hopper by means of the tilting platform or otherwise, and byopening the valve 1 1 it flows out onto the spreader 17, under which thestream of grain passes through the blast delivered from the blower head19, and any chaff, dirt and like matters are blown up through the pipe25 and out to waste. The clean grain passes down through the leg 11 andinto the conveyor, by which it may be taken to the bins of the elevator.

I claim:

1. In a grain separator, in combination, a hopper having sides whichconverge to an outlet at the lower end, a false bottom provided with avalve and extending between the side of the hopper at a distance abovesaid outlet, forming a space in the lower part of the hopper under saidfalse bottom, a spreader standing in said space under the valve, ablower head projecting in said space below the spreader, on one side,and a waste pipe having an enlarged mouth projecting into said spaceopposite the head.

2. In a grain separator, in combination, a hopper having a valve at thebottom, a conical spreader standing under the valve, a blower headlocated below and on one side of the spreader, and. having a perforatedface curved to extend partly around the stream of grain falling from thespreader, and a waste pipe the mouth of which is opposite to the head,on the other side of ti 2 spreader.

In testimony whereof I a'liix my signature, in presence of twowitnesses.
